[Anomalous myocardial vascularization. Case report].

Abstract

A 52 years old woman was surgically treated at her 27 years of age for a defect of atrium septum of IInd type. The defect was covered by a patch taken from pericardium. The operation was followed twice by lung embolism. In 1986 there occurred deterioration of the condition. A recanalization of the defect was detected and the patient was recommended to operation. The operation was preceded by selective coronarography, which proved anomalous vascularization of myocardium in the left atrium. Echocardiography and computer tomography detected a pathological formation in this area. The suggested formation was not found during the operation. The explanation of anomalous vascularization of myocardium is believed to have been caused by a thrombus after the first operation; the thrombus may have caused proliferation of coronary vessels, then paradoxically resulted in lung embolism and the pathological vascularization persisted.
